Supplemental description of Myxobolus squamalis (Myxozoa).
Myxobolus squamalis is a myxozoan skin parasite first reported from rainbow trout (Oncorhynchus mykiss). Identification of the parasite based on myxospore morphology is unreliable because M. squamalis is similar to several other myxobolids that share host species and geographic ranges. The only ssrRNA gene sequence available for M. squamalis is from Chinook salmon, Oncorhynchus tschawytscha, bu...
متن کاملRevision of Myxobolus heterosporus Baker, 1963 (syn. Myxosoma Heterospora) (Myxozoa: Myxosporea) in African records.
There is uncertainty regarding the validity of Myxobolus heterosporus Baker, 1963. The present study revises the taxonomy, using specimens isolated from plasmodia situated in the infected cornea of Oreochromis aureus, O. niloticus or Tilapia zillii inhabiting the River Nile, Egypt. In addition, histological effects of the parasite on the infected tissue were examined. The spores of M. heterospo...
متن کاملMyxobolus absonus sp. n. (Myxozoa: Myxosporea) parasitizing pimelodus maculatus (siluriformes: Pimelodidae), a South American freshwater fish.
A new myxoporean species is described from a freshwater fish in Brazil. Myxobolus absonus sp. n. was found infecting Pimelodus maculatus captured in the river Piracicaba, State of São Paulo, Brazil. Cysts were found free in the opercular cavity. The spores are large (length--15.7 +/- 1.5 microns, width--10.2 +/- 0.7 microns; mean +/- S.D.) and oval in shape, with the anterior end slightly point...
متن کاملDescription of Three New Myxosporean Species (Myxozoa: Myxosporea: Bivalvulida) of the Genera Myxobilatus Davis, 1944 and Myxobolus Bütschli, 1882
The present communication describes three new species of myxosporeans (Myxozoa: Myxosporea: Bivalvulida), Myxobilatus odontamblyopusi sp. n., Myxobolus catmrigalae sp. n. and M. buccoroofus sp. n. from Odontamblyopus rubicundus (HamiltonBuchanan), Catla-Mrigal hybrid carp [male parent fish Catla catla (Hamilton-Buchanan) × female parent fish Cirrhinus mrigala (Hamilton-Buchanan)] and Labeo bata...
متن کاملThe phylogenetic position of Myxobolus carnaticus (Myxozoa, Myxosporea, Bivalvulida) infecting gill lamellae of Cirrhinus mrigala (Hamilton, 1822) based on 18S rRNA sequence analysis
Myxozoans are an economically important group of microscopic parasites best known for the diseases they cause in commercially important fish hosts. The classification of myxosporeans is generally based on the morphology of their myxospores. Without molecular data, it is very difficult to identify new or existing species. DNA sequence information is therefore, a prerequisite to taxonomic and phy...
